Abstract: The spectra of hydrazide acid HN$_3$ adsorbed on the surface of aerosil SiO$_2$, the effect of coadsorbed molecules of 2,6-dimethylpyridine C$_7$H$_9$N and sulfur dioxide SO$_2$, as well as the effect of resonant laser IR radiation at the frequency of stretching vibration of the molecule on the protonation reaction of adsorbed 2,6-dimethylpyridine were studied using IR Fourier spectroscopy at -196 – +20$^\circ$C.

Keywords: adsorption, aerosil, hydroazide acid HN$_3$, IR spectroscopy, resonance IR excitation, hydrazoic acid, hydrogen azide.
